Abstract
Introducing new plants to an area may have both positive and negative effects on the environment, economy and community. To minimise the negative environmental impact of introducing new agricultural species, DPIRD conducts a risk assessment procedure based on widely accepted scientific standards. This report assesses Persian clover (Trifolium resupinatum). Persian clover is an annual clover native to Turkey, Afghanistan, Portugal, Greece, Iran and Iraq. It was introduced to South Australia in the 1950s and grown commercially in the early 1970s. It has become a valuable species for temperate pastures of southern Australia, but is a minor pasture species in south-western Australia. There are two main subspecies of Trifolium resupinatum: var. majus and var. resupinatum. Trifolium resupinatum var. majus has an erect habit, thick hollow stems and large leaflets, but a low level of hard seed (1 - 2 % ) and is utilised as a multi-cut forage crop. Trifolium resupinatum var. resupinatum has a more prostrate habit, thinner stems and smaller leaflets, but a higher proportion of hard seed and higher seed yields.
